can i take 1 dragon(for example) irregular shape from 1 image?

You are asking if you can extract the dragon shape (and the dragon picture itself) from an image.
Right now, I don't know. If I figure it out I will let you know
not the dragon just the shape;)Quote:

Show the image you want to extract the shape from
I would think it's for a mask of some kind or a shadow imageQuote:

Is the dragon image the only image in the picture? Are the pixels that surround the dragon all same color?
As it is possibly do-able but might need a bit of knowledge or 3rd party controls. I use simply use PhotoShop (or similar) and use the magic selection tool! One click and your done.
Just an idea, if background color (white) is all the same color (white) maybe setting all other pixels that are not background color black let's say.
Than your dragon will be black and background white.
Sorry if this is impossible for your case, but I would think something like this is do-able.
Kind of like doing a transparent background, you know!
Maybe even some api can do it for you, mask your image.
maybe i can't express me better(sorry) to both..... i did it before using the bitblt(), but by mistake... i need that for do a Transparency Opacity(instead by pixels).. need speed or i still get flickers. and a need speed for capture a form\container(inclued the controls).Quote:

Your 1st post states how to extract the shape of a dragon from an image. Your other posts are referring to the fact that you cannot express or explain it correctly. Is all you want to know is how to extract the shape?
yes, but using bitblt().Quote:

OK, you want to extract a shape (a dragon but I assume there may be other shapes) from an image using BitBlt for speed reasons. How this will be done depends on the image itself. I need to see the image
just the shape. the dragon is just a sample;)Quote:

Even with BitBlt it will cause flicker! I have done this before, the only way would be using some like DirectX. There is a way to make it with BitBlt without any flickering (I think). You will have to load the images to another picturebox (invisible or offscreen) and replace it with that one, what I mean is that you need to preload the image to another picturebox to remove the flickering which is caused by masking images (when you place a masked image, then the transparent picture on top). If you only paint on a picturebox over and over with BitBlt, it will cause the flickering once in a while!
I might be wrong on this but I have tried this in the past without success (using BitBtl and one picturebox).
If anyone has a example without any kind of flicker I would also like to use it on some of my projects!
Edit:
Ok I have found an old project, might not be the best. Might need some improvement. I did not fix anything I just zipped it and attached it, now it's up to you to see if BitBlt works :).
Hopefully you find out why in my project it still had the flickering! I know I should not have put Timer Interval = 1 but that way its as fast as it can go.
if you put the land together with that tower and then draw it... goodbye flicker;)Quote:
